PRESSURE MEASURING DEVICE Russian patent published in 1998 - IPC

FIELD: measuring of flowing medium pressure. SUBSTANCE: device uses elements sensitive to flexible medium pressure as primary pressure transducer. Device also has single-turn manometric spring with pipe connection and converter of spring vacant end motion. Immovable end of spring is installed at angle of Q_o= 283^o-0,76γ, relative to pipe connection axis where γ - is central angle of spring. Provision is also made for increasing the number of spring turns without reducing the device sensitivity. EFFECT: enhanced sensitivity. 3 cl, 7 dwg
